The TSGC2 and TSGC2J series three-phase contact voltage regulator is an adjustable autotransformer engineered with high-permeability toroidal loop cores and uniformly wound coils. Under uniform spring pressure, the conductive carbon brush maintains tight, precision contact with the polished copper track of the coil winding.
When the heavy-duty rotary handwheel and drive shaft are operated, the carbon brush slides smoothly across the polished commutator surface, seamlessly altering the primary-to-secondary turns ratio. This electromechanical construction provides linear, continuous, and stepless voltage regulation across the entire output range of 0V to 430V AC (3-phase) with ultra-low internal impedance.
Delivers a pure undistorted sine wave matching input utility power, ideal for sensitive industrial machinery and precision electronics.
Toroidal core structure minimizes magnetic flux leakage, optimizing footprint and volume for streamlined cabinet integration.
Low no-load losses and high operating efficiency reduce operating costs across industrial test lines and continuous production.
Equipped with high-wear-resistant composite carbon brushes and calibrated control dial for instant, flicker-free manual output tuning.
Rated for long-term continuous operation under ambient conditions with excellent thermal endurance and dependable structural rigidity.
Due to their dependable electrical stability and continuous output performance, the TSGC2 & TSGC2J series voltage regulators are widely applied across multiple industrial manufacturing sectors, R&D laboratories, and infrastructure systems:
